X² + ((1.5x + 3) - 3)² = 16
<span>x² + (1.5x)² = 16 </span>
<span>x² + 2.25x² = 16 </span>
<span>3.25x² = 16 </span>
<span>x = 8√(13)/13 </span>
<span>x ≈ 2.219 </span>
<span>and so </span>
<span>y = 1.5(8√(13)/13)+ 3 </span>
<span> ≈ 6.328 </span>
<span>so </span>

Number of cups of sugar Ricky needs =
Number of cups of sugar Ricky already has =
Hence, number of cups of sugar Ricky requires =
2x+3 + 4x+2 + 2x-1 = 8x + 4 = 4(2x+1). nothing else to do if that's all the information given
